iC7-Marine

The iC7-Marine is the ideal inverter for controlling electric motors on board vessels, combining energy efficiency with a compact design and the maximum robustness required for the marine environment.
It serves as a power regulator for electric propulsion motors, converting electrical energy from the ship’s grid into perfectly controlled power. This ensures efficient thrust and superior maneuverability, allowing for smooth and instantaneous transitions between different energy sources.
It is the component that turns electrification strategy into an operational, safe, and efficient reality by intelligently managing the energy flows that make ships cleaner, more economical, and higher-performing.
